Am about to install a new solar panel rated at 80w so I guess I'm looking at 4-5 amps at best.
The panel will require a cable run of ~10m to the batteries.
Do I need special solar cable for this installation? The table I found suggests that I would need AWG 11 for this purpose. This apparently equates to 2.5mm or 4mm squared. Plenty of suppliers on fleabay but its not clear whether they are sizing in mm or mm squared.
My brain hurts. Help.
